Inner Barrel Prometheus EG 6.00 GBB Tokyo Marui M4A1 MWS 370 mm

Increase the accuracy of your Tokyo Marui M4A1 MWS with this Prometheus EG 6.00 GBB 370 mm inner barrel.

Thanks to the extremely tight diameter of this inner barrel of only 6.00 mm, the BBs are guided through this barrel very precisely and with more pressure. And at 370mm, this barrel also offers extra length over the standard Tokyo Marui M4A1 MWS inner barrel, which is 250mm long. This also affects the power of the replica.

The Prometheus EG 6.00 GBB Tokyo Marui M4A1 MWS 370mm inner barrel, thanks to its stainless steel construction, can withstand the extra wear and tear that the gas vapors can cause on standard inner barrels.
